Item 5.         Other Events.

         On February 12,  1997,  the  Registrant  and  substantially  all of its
subsidiaries (collectively, the "Company Sellers"), other than Renal Management,
Inc. ("RMI") signed a definitive  agreement to sell  substantially  all of their
operating assets to IHS of New York, Inc., a privately held company ("IHS").  In
addition,  Alpha  Administration Corp. ("Alpha") and Continental Dialysis Center
of the Bronx, Inc. ("CDBI"), each a New York corporation,  a consulting customer
of the  Registrant's  subsidiaries and wholly-owned by officers and directors of
the  Registrant  signed  the  definitive  agreement,  thereby  agreeing  to sell
substantially  all of their operating  assets to IHS. Upper  Manhattan  Dialysis
Center, Inc. ("UMDC"), a New York corporation which is 50% owned by officers and
directors of the Registrant is a signatory to the definitive  agreements but has
not executed the same. The officers and directors of the  Registrant  owning 50%
of UMDC have granted an option to IHS to acquire their interests in UMDC in the
event UMDC does not approve the  transaction,  subject to  restrictions
contained  in certain existing  agreements.  Alpha, CDBI and UMDC are referred
to collectively herein as the "Consulting Customers."

         The purchase  price for the assets to be sold,  including the assets of
the Consulting Customers,  is $13,120,000.  The Purchase Price will be allocated
as of the closing of the transaction.  In addition,  the Registrant and IHS will
enter into a  Consulting  Agreement  pursuant to which  certain  officers of the
Registrant will provide  consulting  services to IHS in exchange for payments to
the Registrant aggregating $1,000,000 over the three year term of the agreement.
$1,000,000  of the purchase  price will be placed in an escrow at the closing of
the  proposed  transactions  to  secure  certain  indemnity  obligations  of the
Registrant  to IHS.  The funds  placed in escrow  will,  unless  used to satisfy
indemnity  obligations  to IHS, be released to the  Registrant  over an 18 month
period.

         The definitive  agreements are subject to approval by the  shareholders
of the  Registrant.  The  closing  of the  transaction  is  subject  to  certain
conditions, including without limitation,  completion of due diligence by IHS on
or  before  March  15,  1997,  governmental  approvals,  completion  of  certain
transactions  involving  Consulting  Customers  and the  continuing  accuracy of
certain  representations  and warranties  contained in the definitive  agreement
among the parties.

         The  Registrant  will  agree not to  compete  with IHS in the  dialysis
treatment and certain  related  businesses for a period of five years  following
the closing of the proposed  transactions.  The covenant not to compete does not
restrict RMI from engaging in the renal disease state  management  and physician
practice management businesses.  TechTron, Inc., the holder of approximately 48%
of the outstanding common stock of the Registrant has agreed to vote in favor of
the proposed  transaction.  International Health Specialists,  Inc., a privately
held company  affiliated  with IHS guaranteed  the  obligations of IHS under the
terms of the definitive agreement.

The Registrant  will continue in business  following the closing of the proposed
transactions.

its  stockholders  adopt and approve the execution,  delivery and performance of
this  Agreement,  unless it is  advised in  writing  by  outside  legal  counsel

                  or  obligations  of any  nature,  whether  accrued,  absolute,
                  contingent,  primary  or  secondary,  direct or  indirect  (by

                  otherwise,  and whether due or to become due (including  bonds
                  posted  and  guaranties  given),  other than  obligations  and
                  liabilities  incurred  since December 31, 1995 in the ordinary

                           C.  Assets.  Exhibit  1.1  contains  a  complete  and
                  accurate list, arranged by Seller,  identifying and specifying
                  the location,  and the direct owner  thereof,  of all tangible
                  Assets of each  Seller or used by any Seller in the  operation
                  of the Business,  and all warranties related thereto.  Each of
                  the Sellers  owns and at the Closing  will own its  respective
                  Assets free and clear of all claims, liens, security interests
                  and  encumbrances,  except for liens to be  discharged or paid

                  spare  parts),  (ii) fit for the  purpose  for which  they are
                  used, and (iii) where used or retained for purposes other than
                  spare parts,  maintained  consistently  in accordance with the
                  manufacturer's  recommendations.  Except as  specifically  set

                  knowledge,  the Assets and the use  thereof by the  Sellers in
                  the Business complies with all applicable governmental laws or
                  regulations,   and  there  are  no  adverse  circumstances  or
                  conditions  that may interfere  with Buyer's use of the Assets
                  in the conduct of the Business immediately after the Closing.

                  and  Sellers  will supply the date of hire of each such person
                  on or before  February 23,  1997.  Except as set forth in such
                  exhibit, no Seller has a written employment agreement with any
                  employee,  and no Seller is a party to any union  contract  or
                  any  qualified or  nonqualified  pension,  profit-sharing,  or
                  similar  retirement  or employee  benefit  plan,  or any other
                  compensation arrangement.

                           E. Inventory.  The inventory of Sellers consists, and
                  at the  Closing  will  consist,  of  items  of a  quality  and
                  quantity useable in the ordinary course of the Business and is
                  no less  inventory  than necessary to conduct the Business for
                  fourteen (14) business days.

                           F.  Conduct  in  the  Ordinary  Course  of  Business.
                  Between  the  date of this  Agreement  and the  Closing,  each
                  Seller will  operate and  maintain  the  Business in the usual
                  course, will take no corporate action out of the ordinary, and

                  than Excluded  Assets);  increasing the compensation of any of
                  its employees  who are to be  terminated  by Sellers  pursuant

                  other  than such of these  enumerated  actions as may arise in
                  the normal and usual  course of  business  as  conducted  on a
                  day-to-day basis or as may otherwise be approved in writing by
                  Buyer.  Notwithstanding the foregoing,  Buyer acknowledges and
                  approves the payment for and  financing(if  desirable)  of the
                  dialysis  units obtained since July 1996 listed on Exhibit 6.9
                  hereto. The salary and fringe benefit package of new employees
                  of  the   Business  (if  other  than   consistent   with  past
                  practices),  and the identity of and the arrangement  with any
                  medical director must be approved in writing by Buyer.

                           G. Compliance with Laws. That, except as disclosed on
                  Exhibit 6.4 hereto,  the Sellers' operation of the Business as
                  of  this  date  is,  and as of the  Closing  Date  will  be in
                  compliance with all applicable laws, rules, and regulations of
                  the city,  county,  state, and federal  governments  including
                  without limitation,  all applicable health, safety, pollution,
                  equal opportunity  (including  affirmative action compliance),
                  and ERISA laws or regulations.  None of the Sellers is a party
                  to any  administrative  proceeding before any state Department
                  of Public Health Services or any similar agency,  or any other
                  state or federal  agency  which  governs  the  Business or the
                  operation   and   conduct   of  the   Business,   nor  is  any
                  administrative  order  pending  as to  any  such  agency.  All
                  permits,  licenses,   accreditations,   consents,   approvals,
                  franchises,  certificates of need,  certifications,  and other
                  authorizations  and  the  like  (the  "Licenses",   including,

                  Administration)  necessary to operate the  Business  have been
                  obtained  by each  Seller,  are  valid  and in full  force and
                  effect,  and a list of each is attached as Exhibit 6.5 hereto.
                  None of the Sellers  engages in any activity which would cause
                  revocation or suspension of any such License or the like,  and
                  no  action  or  proceeding  looking  to or  contemplating  the
                  revocation or suspension thereof is pending or threatened, nor
                  have any of the Sellers  engaged in any  activity  which would
                  cause  revocation  or  suspension  of any such  License of the
                  Buyer following the Closing.

                           H. Litigation.  Except as set forth on Exhibit 6.6 to
                  this Agreement:  (i) there are no actions, suits,  proceedings
                  or investigations (whether or not purportedly on behalf of any

                  federal,  state,  municipal or other governmental  department,
                  commission,    board,    bureau,    agency,    arbitrator   or
                  instrumentality,  domestic or foreign,  pending or threatened,
                  anticipated  or  contemplated  against,  by, or affecting  any
                  Seller,  or the  transactions  contemplated by this Agreement,
                  including, but not limited to,

                  suits,   proceedings  or  investigations   which  question  or
                  challenge  the validity of this  Agreement or any action taken
                  or to be taken by  Seller  pursuant  to this  Agreement  or in
                  connection  with  the  transactions  contemplated  hereby;  or
                  which, if valid, would constitute or result in a breach of any
                  representation,  warranty or agreement  contained herein;  and
                  (ii) there is no valid basis for the  commencement of any such
                  claims, actions, suits, proceedings or investigations. Sellers
                  will update Exhibit 6.6 hereto, to the Closing Date to include
                  any  litigation,  proceeding,  or material claim of any nature
                  whatsoever  pending or  threatened  against the Sellers or any
                  one of them,  and will as of the Closing Date  represent  that
                  none of the Sellers know or have reasonable grounds to know of
                  any basis for any claim,  proceeding or litigation against the
                  Sellers or any one of them, other than the claims, proceedings
                  or litigations listed on Exhibit 6.6, as updated.

                           I. Absence of Changes. Except as set forth on Exhibit
                  6.7 to this  Agreement and for changes in the ordinary  course

                                    (b)  loss of  contract  rights  or  business
                                    relationships of Seller, or

                                    (c) change,  occurrence  or situation of any
                                    kind, nature or description;

                           which, individually or in the aggregate, has resulted
                           in, or is reasonably  likely to result in, a material
                           adverse change in the business, operations, earnings,
                           backlog, prospects,  properties,  assets, liabilities
                           (absolute,  accrued, contingent or otherwise, whether
                           due  or  to  become  due),  reserves,  or  condition,

                           encumbrance  of any  nature  whatsoever  placed on or
                           against  any of  Seller's  property or assets used in
                           the conduct of the Business; or

                           (iii)  any   material   change  in  the  business  or
                           commercial practices customarily followed by Seller.

                  Seller knows of no impending  loss of customers,  suppliers or
                  employees of Seller that might have a material  adverse effect
                  on the Business, or which might prevent Buyer from carrying on
                  such Business in substantially  the same manner in which it is
                  carried on at the date of this Agreement.

                  contracts  relating to the Business to which the  Sellers,  or
                  any one or more of them,  are a party or by which the Sellers,
                  or any one or more of them,  may be bound in excess of $5,000.
                  Complete  copies  of such  documents  have been  delivered  to

                  therein  and/or of any  alleged  default  on behalf of Sellers
                  under any such  contract nor are the Sellers  aware of any act
                  or omission on behalf of any of the Sellers or any event which
                  with the  passage of time will  entitle  any party to any such
                  contract   other  than  the   Sellers  to  declare  a  default
                  thereunder  or to  entitle  such party to  terminate  any such
                  contract.

                  the federal  Medicare  program as an end-stage  renal  disease
                  ("ESRD")  facility  providing ESRD  services.  Each Seller has
                  delivered to Buyer complete and correct copies of all surveys,
                  reports or deficiency notices concerning the Facilities by the
                  Medicare program, the state

                  survey  agency,  the  Medicaid  program or the Kidney  Disease
                  Program; and all corrective actions set forth in any filing by
                  the Sellers in response to deficiencies identified by: (i) the
                  New York or New  Jersey  Departments  of  Health,  or (ii) the
                  federal  Department  of  Health  and  Human  Services,  in any
                  monitoring  survey  of any  Seller  (all of  which  have  been
                  delivered  to Buyer),  have been  accepted  by such agency and
                  completed by such Seller,  and that, to the best  knowledge of
                  Sellers, no further deficiencies exist. Except as set forth on
                  Exhibit  6.10  hereto,  the  Medicare  certification  of  each
                  Facility is in full force and effect and no  violation  of the
                  conditions  and  standards  of  coverage,   participation   or
                  certification  with respect to the  Facilities  exists and, to
                  each Seller's knowledge, no event or circumstances exist which
                  with the giving of notice or passage of time,  or both,  would
                  constitute  a material  violation  thereof  such as to have an
                  adverse  effect  upon the use or  operation  of the  Assets or
                  Business by the Buyer following the Closing.

                           M. No Falsehoods or Omissions.  No statement  made by
                  any  Seller  in any  certificate,  document,  list or  exhibit
                  furnished  to  Buyer  in  connection  with  this   transaction
                  contains or will  contain any untrue  statement  of a material
                  fact,  or omits to state or will omit to state a material fact
                  necessary to make the statement contained herein or therein in
                  light  of  the  circumstances  under  which  it was  made  not
                  misleading.  True and correct copies of all documents referred
                  to on the exhibits  hereto as  currently in effect,  have been
                  delivered to Buyer.

                           N.  Insurances.  Exhibit  6.11(a) is a list and brief
                  description  of all  policies  or binders of fire,  liability,
                  product  liability,  worker's  compensation,  health and other
                  forms of  insurance  policies  or binders  currently  in force
                  insuring the Sellers  against  risks which will remain in full
                  force and effect (or will be replaced by substantially similar
                  coverage) at least through the Closing Date.  Exhibit  6.11(b)
                  contains a description of all malpractice  liability insurance
                  policies  of the  Sellers.  Except  as set  forth  on  Exhibit
                  6.11(c),  (i) no Seller has ever  filed a written  application
                  for  any  insurance  coverage  which  has  been  denied  by an
                  insurance  agency or  carrier  and (ii) each  Seller  has been
                  continuously  insured for professional  malpractice claims for
                  the lesser of (a) the period from the inception of such Seller
                  until the date hereof or (b) the past seven (7) years. Exhibit
                  6.11(c)  also sets forth a list of all claims for any  insured
                  loss in excess of $5,000 per occurrence,  filed by such Seller
                  during the three (3) year  period  immediately  preceding  the
                  Closing  Date,   including   but  not  limited  to,   worker's
                  compensation,  general liability,  environmental liability and
                  professional malpractice liability claims. None of the Sellers
                  is in material default with respect to any provision contained
                  in any such  policy and none of the Sellers has failed to give
                  any notice or present  any claim  under any such policy in due
                  and timely fashion.

                  of  contracts,  will not  result in a breach,  declaration  of
                  default,  or  otherwise  adversely  affect  any  debt,  lease,
                  agreement or other obligation or contract or liability of such
                  Seller except as may be waived in writing by Buyer.

                           E. That the  Sellers  shall  deliver  to the Buyer at
                  Closing  an  opinion  of  counsel  to the  Sellers in form and
                  substance  satisfactory  to counsel  for Buyer,  to the effect
                  that, as of the Closing:

                                    (i)  Each  Seller  is  a  corporation   duly
                           organized,  validly  existing  and in  good  standing
                           under the laws of the state of its incorporation;

                                    (ii) Each Seller has full corporate power to

                           Agreement;   all  corporate  and  other   proceedings
                           required to be taken by or on the part of each Seller
                           to authorize it to execute and deliver this Agreement
                           and to consummate the  transactions  contemplated  by
                           this Agreement have been duly and validly taken;  and
                           this Agreement has been duly and validly  authorized,
                           executed,  and  delivered  by  each  Seller  and is a
                           legally binding obligation of each Seller enforceable
                           in accordance with its terms;

                                    (iii) Neither the sale of the Assets nor the
                           transactions  contemplated by this Agreement  require
                           compliance  by any Seller with the  provisions of any
                           statutes or regulations applicable to the transaction
                           contemplated   by   this   Agreement,    other   than
                           potentially  the New York or  Connecticut  Bulk Sales
                           Act; and

                                    (iv) The consummation of this Agreement will
                           not (a) give rise to or cause any  default  under any
                           of the terms, conditions,  or provisions of any note,
                           bond, mortgage, indenture, license, agreement, or any
                           other instrument or obligation to which any Seller is
                           a party or by which  it or any of its  properties  or
                           assets may be bound which are known to counsel  after
                           reasonable inquiry of the Sellers, or (b) violate any
                           court order, writ,  injunction,  or decree applicable
                           to any Seller or any of its properties or assets.

                  Such opinion of counsel may take  exception  for or be subject
                  to matters such as the rights of creditors  generally  and the
                  discretion of a court to grant  equitable  remedies,  and once
                  prepared  shall be  appended  hereto  as  Exhibit  7.1 to this
                  Agreement.

                  expiration of applicable  waiting periods)  required under the
                  Hart-Scott-Rodino  Antitrust  Improvements  Act of  1976.  The
                  parties  agree to prepare in good faith and to prosecute  with
                  due diligence all applications for the governmental approvals.

                           H. The execution and  consummation of this Agreement,
                  the  representations,  warranties  and  covenants  of  Sellers
                  herein contained,  and the transactions described herein shall
                  have been fully ratified, adopted and approved by the Board of
                  Directors  and the  Stockholders  of UMDC,  and this  document
                  shall have been duly  executed  on behalf of UMDC by March 31,
                  1997 or Buyer shall have  exercised  the option on UMDC shares
                  set forth at the foot of this Agreement.

                           I. The execution and  consummation of this Agreement,
                  the  representations,  warranties  and  covenants  of  Sellers
                  herein contained,  and the transactions described herein shall
                  have been fully ratified,  adopted and approved by CCC's Board
                  of Directors by February 23, 1997 and by the  Stockholders  of

                  has approved the execution and delivery of this  Agreement and
                  all Schedules,  Exhibits and due diligence  materials required
                  of Sellers shall have been delivered to Buyer.


                           J. CCC shall have entered into a Consulting Agreement
                  with  Buyer  agreeing  to  provide  the  services  of  certain
                  officers  of Seller  identified  therein in the form  attached
                  hereto  as  Exhibit  7.2,  and  each  of the  Sellers  and the
                  Affiliated  Entity,  and the  respective  executive  officers,
                  directors and  affiliates  of each,  shall have entered into a
                  Non-Competition  Agreement  with  Buyer in the  form  attached
                  hereto as Exhibit 7.3.

                           K. The Sellers shall have  purchased  tail  insurance
                  for extension of protection  afforded by the current  policies
                  of  liability  insurance  for at least a five  year  period as
                  provided in Section 12.C herein, or shall have demonstrated to
                  Buyer's satisfaction in its sole discretion, that the policies
                  they  have in place  will  provide  coverage  in all  respects
                  identical  to that  which  would  be  provided  by  such  tail
                  insurance.

                           L.  Effective  at Closing,  (i) all  employees of the
                  Facilities  and the  Business  designated  by Buyer shall have
                  been  terminated  by the  Sellers and hired by Buyer (with the
                  exception of the  administrative  employees of CCC's corporate
                  office), (ii) all accrued salary, sick leave and vacation time
                  shall be paid to such employees by the Sellers,  and (iii) all
                  employee benefit plans shall have been



                                       15
<PAGE>
                  treated by Sellers as  partially  terminated  with  respect to
                  such employees,  unless such plans are fully terminated by the
                  Sellers.

                           M. On or before the  Closing  Date,  the Buyer  shall
                  have been duly licensed in the States of New York,  New Jersey
                  and Connecticut,  as applicable, to operate the Facilities and
                  the  Business  as it is  operated  by the  Sellers on the date
                  hereof,  and  Buyer  shall  have  obtained  or  applied  for a
                  Medicare  provider  number  for the  Facilities  and all other
                  necessary   accreditations,   authorizations,   consents   and
                  approvals  necessary  to  operate  the  Business,   the  Buyer
                  agreeing  to use  reasonable  best  efforts  with  respect  to
                  obtaining the same.

                           N. On or before the Closing, Buyer shall have entered
                  into an agreement with one or more  nephrologist(s)  to act as
                  medical  director(s)  of  each  of  the  Facilities;  provided
                  however that this  condition  shall be deemed to have been met
                  unless Buyer shall have failed to enter into  agreements  with
                  such  nephrologists  as  it,  in  its  sole  discretion,   has
                  identified as candidates  for such  position(s),  after having
                  made  offers of  compensation  and other  terms of  employment
                  reasonably  similar to those enjoyed by individuals  currently
                  in Buyer's employ in similar  positions;  and provided further
                  that if Buyer  determines  to offer any of  Sellers'  existing
                  medical  directors a continuing  position  (and makes no other
                  offer)  the  condition  will not be deemed to have been met if
                  Buyer  fails to offer  such  physician  compensation  at least
                  equal to that which he has been  receiving  as of December 31,
                  1996.

                           O. Buyer shall have completed its  investigation  and
                  examination  of the  ownership,  condition,  and nature of the
                  Assets;  the  financial   condition  and  operations  of  each
                  Facility; and the business, affairs, books and records of each
                  of the  Sellers in a "due  diligence  investigation";  and the
                  results thereof shall have been deemed  acceptable by Buyer in
                  its  sole  discretion  with  respect  to  each  Seller.   Such
                  condition shall be deemed  satisfied unless Buyer shall notify
                  Sellers in writing on or before March 15, 1997,  or such later
                  date as may be two weeks following the receipt by Buyer of the
                  December 31, 1996 edition of the Financial  Statements,  as to
                  the matters which are not  acceptable,  or as to which matters
                  have not been fully disclosed.


                  Section 8.  Conditions to Obligations of Sellers:

                  All  obligations  of the  Sellers  under  this  Agreement  are
subject  to the  fulfillment,  on or before  the  Closing  Date,  of each of the
following conditions, any or all of which may be waived by the Sellers:

                           A. All the terms,  conditions,  and covenants of this
                  Agreement  to be complied  with and  performed  by Buyer at or
                  before the Closing Date shall have been duly complied with and
                  performed.

                           B.  Buyer  shall  have  delivered  to the  Sellers at
                  Closing an opinion of its counsel that as of the Closing Date:

                                    (i)  The   Buyer  is  a   corporation   duly
                           organized,  validly  existing  and in  good  standing
                           under the laws of the state of its incorporation;

                                    (ii) The Buyer has full  corporate  power to
                           carry  out  the  transactions  provided  for in  this
                           Agreement;   all  corporate  and  other   proceedings
                           required  to be  taken  by or on the part of Buyer to
                           authorize  it to execute and deliver  this  Agreement
                           and to consummate the  transactions  contemplated  by
                           this Agreement have been duly and validly taken;  and
                           this Agreement has been duly and validly  authorized,
                           executed,  and  delivered  by Buyer  and is a legally
                           binding obligation of Buyer enforceable in accordance
                           with its terms; and

                                    (iii) The execution of this  Agreement,  and
                           the exhibits thereto,  and such additional  documents
                           required to be executed or delivered by the Buyer and
                           the  consummation  of  the  transaction  contemplated
                           hereby  do not  violate  any  agreement  to which the
                           Buyer is a party  which is  known  to  counsel  after
                           reasonable  inquiry of the Buyer, or any court order,
                           injunction  or decree  applicable  to Buyer,  and are
                           enforceable in accordance with their terms.

                  Such opinion of counsel may take  exception  for or be subject
                  to matters such as the rights of creditors  generally  and the
                  discretion of a court to grant  equitable  remedies,  and once
                  prepared  shall be  appended  hereto  as  Exhibit  8.1 to this
                  Agreement.

                           C. Buyer shall have  assumed the  obligations  of the
                  Sellers  under the contracts it agrees to assume as identified
                  on Exhibit 1.2 hereof,  subject to the  required  consents and
                  approvals of third parties disclosed herein.

                           D. The execution and  consummation of this Agreement,
                  the  representations,  warranties  and  covenants  of  Sellers
                  herein contained,  and the transactions described herein shall
                  have been fully ratified, adopted and approved by the Board of
                  Directors  and the  Stockholders  of UMDC,  and this  document
                  shall have been duly executed on behalf of UMDC or Buyer shall
                  have exercised the option on UMDC shares set forth at the foot

                           E.  Buyer  shall  have   entered  into  a  Consulting
                  Agreement with CCC and the individuals named therein, agreeing
                  to  provide  the  services  of  certain   officers  of  Seller
                  identified therein in the form attached hereto as Exhibit 7.2.

                           F. The execution and  consummation of this Agreement,

                  herein contained,  and the transactions described herein shall
                  have been fully ratified,  adopted and approved by CCC's Board
                  of Directors by February 23, 1997 and by the  Stockholders  of
                  CCC

                           G. The  transactions  contemplated  hereby shall have
                  been  approved  by all  applicable  federal,  state  and other
                  governmental  authorities  and agencies  which are required to
                  approve same including,  but not limited to, any approvals (or
                  expiration of applicable  waiting periods)  required under the
                  Hart-Scott-Rodino  Antitrust  Improvements  Act of  1976.  The
                  parties  agree to prepare in good faith and to prosecute  with
                  due diligence all applications for the governmental approvals.


                  Section 9.  Risk of Loss:

                  It is  understood  and agreed that pending the Closing and the
parties'  delivery  of the  instruments  of  transfer  referred  to in Section 2
hereof,  the Buyer does not assume and shall not in any event be  responsible or
liable  for,  any loss or  damage  to any of the  properties  and  assets  to be
transferred  hereunder from any cause whatsoever,  whether by fire,  casualty or
otherwise.  In the event any such loss occurs  prior to the  Closing,  or in the
event any  Facility is closed or  interrupted  by reason of any event not in the
ordinary  course of its  business,  the Buyer shall have the right to  terminate
this Agreement on written notice to Sellers, or to make an equitable  adjustment
to the Purchase Price reasonably acceptable to Seller with respect to such loss,
damage or action. All risk of loss after the Closing shall be borne by Buyer.


                  Section 10.  Adjustments; Prorations:

                 A. The Purchase  Price shall be adjusted  dollar for dollar for
any Assumed  Liabilities,  other than (i) real estate  leases and (ii) except as
set forth on Exhibit 1.3.

                  B.  Any  liability,  accrued  or  unaccrued,  for  taxes  from
operation of the Facilities or the Business prior to Closing shall be discharged
by the Sellers  promptly and in their entirety.  Any taxes from operation of the
Facilities  or the Business  after the Closing Date shall be  discharged  by the
Buyer in their entirety. For this purpose,  "taxes" shall include federal income
taxes,  and any and all business  related taxes  including,  but not limited to,
franchise and excise taxes,  sales and use tax, gross receipt  taxes,  state and
federal  employee  income tax  withholding,  Federal Social  Security Tax (FICA)
withholding,  employment taxes, ad valorem personal property taxes, and business
or license fees or any other tax  applicable to the  Facilities or the Business.


                                       18
<PAGE>

In no event  shall Buyer be liable for income,  transfer,  sales,  use and other
taxes arising from or in connection with the  consummation  of the  transactions
contemplated hereby.


                  Section 11.  Indemnification:

                  A. The Sellers  jointly and severally agree to indemnify Buyer
from and with respect to any and all loss,  liability,  or  additional  expense,
including  reasonable  attorney's fees, as Buyer may incur from and with respect
to any material  misrepresentation  made herein, or in any schedule,  exhibit or
other  document  executed by the Sellers or delivered  by them  pursuant to this
Agreement,  or for any material  breach of any Seller's  warranties or covenants
imposed herein upon the Sellers or made herein by the Sellers, whether due to an
undisclosed  or  understated  liability  of the  Sellers,  or from any action or
inaction of the Sellers on or prior to the Closing Date, including specifically,
but not limited to, any and all expenses,  costs and liabilities  that may arise
as a result of the  failure of the parties to comply with the Bulk Sales Acts of
the  States of New  York,  New  Jersey or  Connecticut,  if  applicable,  and to
indemnify and hold harmless Buyer and its affiliates  from any and all expenses,
costs and for liabilities associated therewith.

                  B. The Buyer  agrees to  indemnify  the Sellers  from and with
respect  to any  and all  loss,  liability,  or  additional  expense,  including
reasonable  attorney's  fees, as any one or more of them may incur from and with
respect to any  material  misrepresentation  made  herein,  or in any  schedule,
exhibit or other document  executed by Buyer or delivered by it pursuant to this
Agreement, or for any material breach of Buyer's warranties or covenants imposed
herein upon the Buyer or made herein by the Buyer, whether due to the failure of
Buyer to perform an executory  contract assumed by the Buyer, or from any action
or inaction of the Buyer after the Closing Date, or otherwise.

                  C.  The  rights  of  any  party  seeking  recourse  under  the
indemnification  provisions  of this  Agreement  must be  asserted  by filing an
action in a court of appropriate  jurisdiction or by delivering a written notice
of the  claim for  indemnification  to the party  from whom  indemnification  is
sought within two (2) years after the Closing Date, unless the claim so asserted
(i)  relates  to a  medical  malpractice  claim  or  is  attributable  to  loss,
liability,  expenses or claims made by any federal,  state or local  government,
governmental agency or governmental payor for health services, in which instance
the  indemnification  claim must be  asserted  within  three (3) years after the
Closing  Date;  or (ii) relates to the failure to pay the proper amount of taxes
(as  such  term  is  used  in  Section  10(B)  hereof)  in  which  instance  the
indemnification claim must be asserted within three (3) years from the later of:
(a) the date the tax  return  for  such tax was  filed,  or (b) the date the tax
payment was due to be paid to an  appropriate  taxing  authority,  including any
extensions;  or (iii)  relates to any loss,  liability or cost  described in the
last sentence of Section 4.D, in which instance the indemnification claim may be
asserted  within  two years  after the date the party  claiming  indemnification
receives notice of such loss, cost or liability.

                  D. In no event  shall  there be any  recourse  by Buyer to the
provisions for  indemnification  under this Agreement unless the amount of loss,
liability,  or expense actually  incurred by Buyer seeking to exercise the right
to  indemnification  under  this  Agreement  exceeds  $100,000  with  all  loss,


                                       19
<PAGE>

liability or expense (net of related  insurance  recovery)  associated with this
Agreement.  In such event the right of any party to enforce this indemnification
provision shall be all loss,  liability,  or expense, not just that in excess of
$100,000. Notwithstanding the above, the restrictions set forth in the preceding
two  sentences  shall not apply  with  respect  to: (i) any loss,  liability  or
expense actually  incurred which relates to: (i) any liability for taxes as such
term is used in Section 10.B. hereof;  (ii) any liability or obligation to third
parties which is not specifically assumed by Buyer; or (iii) any liability, cost
or loss described in Section 4.D(i).

                  E. Notwithstanding the previous provisions of this Section 11,
the  covenants,  warranties,  representations,  and  obligations  of the parties
regarding:  (i) Buyer's  obligation  to indemnify  the Seller for the  executory
contracts and agreements  assumed pursuant to Section 1.B. shall survive for the
life of such contracts  and/or  agreements;  (ii) the parties'  obligations  and
covenants which by the terms hereof are to be performed hereafter, shall survive
for the periods within which such  performance  is to occur,  plus 180 days; and
(iii) Sellers' warranties and representations of title shall not expire.


                  Section 12.  Post-Closing Covenants:

                  A. Cooperation. The Parties agree to cooperate with each other
in the  preparation  and  filing  of any  federal,  state or other  governmental
reports  or filings  required  to be filed by any of them as a result of or with
respect to the transactions  contemplated  hereby.  Each such return,  report or
filing shall be reviewed by the non-filing  parties,  and its truth and accuracy
confirmed,  to the best of such parties'  knowledge,  in writing,  such that the
return may be timely filed.

                  B.  Discharge of Debts.  Sellers  jointly and severally  agree
promptly and in due course to discharge  any and all of the debts,  claims,  and
expenses of each Seller which relate to the Business or the Facilities and which
are not  specifically  assumed or agreed to be discharged  by Buyer  pursuant to
this  Agreement.  The  liabilities to be discharged by the Sellers shall include
without limitation:  [i] all short-term or long-term liabilities of the Sellers,
whether  or not shown on the books of the  Sellers as of the  Closing;  [ii] any
liabilities  whether or not  required by GAAP to be recorded on the books of the
Sellers for  accrued  vacation  and sick pay leave,  compensatory  time  medical
insurance   benefits,   qualified  plan  benefits  and  other   employee-related
obligations  through the Closing;  [iii] all taxes which relate to the operation
of the Business by the Sellers through the Closing,  including  liability of the
Sellers  for  federal  income  taxes or New  York,  New  Jersey  or  Connecticut
franchise and excise taxes,  sales,  use or other taxes for that portion of 1997
which ends with the Closing Date;  [iv]  liability for all sums payable to third
parties for goods or services  ordered by, shipped to or received by the Sellers
at



                                       20

                  Section 14.  Termination:

                 A. Any party to this  Agreement  may terminate  this  Agreement

                           (i) the  parties  may  terminate  this  Agreement  by
                  mutual written consent at any time prior to the Closing Date;

                           (ii) the Buyer may terminate this Agreement by giving
                  written  notice to the  Sellers at any time prior to or at the
                  Closing,  (a) in the event that any Seller  has  breached  any
                  representation,   warranty,  or  covenant  contained  in  this
                  Agreement  in  any  material  respect,   (b)  if  Buyer  shall
                  determine that: (I) the transaction has become  inadvisable or
                  impracticable  by reason of the  institution  or threat by any
                  state,  local or federal  governmental  authorities  or by any
                  other person of material litigation or proceedings against any
                  of the parties hereto or any of the entities  controlled by or
                  affiliated  with such entities  pertaining to or affecting the
                  transaction;  or (II) the  business  or  assets  or  financial
                  condition of any of the Sellers hereto individually, or in the
                  aggregate, has been materially and adversely affected, whether
                  by reason of  changes or  developments  or  operations  in the
                  ordinary course of business since December 31, 1996, or (c) if
                  the Closing shall not have occurred on or before September 30,
                  1997,  and the failure to so close relates to  conditions  not
                  met by Sellers;

                           (iii) the Sellers may  terminate  this  Agreement  by
                  giving  written notice to the Buyer at any time prior to or at
                  the  Closing:  (a) in the event  that Buyer has  breached  any
                  representation,   warranty  or  covenant   contained  in  this
                  Agreement in any material  respect;  (b) the  transaction  has
                  become inadvisable or impractical by reason of the institution
                  or  threat  by  any  state,  local  or  federal   governmental
                  authorities  or by any other person of material  litigation or
                  proceedings  against any of the  parties  hereto or any of the
                  entities   controlled   or   affiliated   with  such  entities
                  pertaining  to or  affecting  the  transaction;  or (c) if the
                  Closing  shall not have  occurred on or before  September  30,
                  1997 and the  reason for the  failure  to so close  relates to
                  conditions not met by Buyer; or





                                       22

                           (iv)  notwithstanding  the provisions of clauses (ii)
                  or (iii)  hereof,  either the  Sellers or Buyer may  terminate
                  this  Agreement by giving written notice to the other party if
                  the  requisite  governmental  approvals  and licenses have not
                  been  obtained by August 31, 1997 but not sooner,  despite the
                  reasonable  best  efforts  of the  terminating  party,  unless
                  extended by the mutual consent of the parties.

If Buyer or Sellers  asserts or assert the  existence  of a breach  pursuant  to
clauses (ii) or (iii) of this Section  14.A.,  the party  asserting  such breach
shall so notify the other party in writing. Such notice shall include a specific
statement as to the act,  omission or breach which  specifically  sets forth the
corrective action which the party asserting such breach contends is necessary to
cure the breach, or if no such cure is possible, a statement to that effect. The
other party  shall be given a period of thirty  (30) days  within  which to cure
such  alleged  breach,  if  capable  of  being  cured,  and the  closing  of the
transaction shall be extended during such thirty (30) day period.

                  B. If any Party terminates this Agreement  pursuant to Section
14.A. above, all rights and obligations of the parties hereunder shall terminate
without any  liability of any party to any other party (except for any liability
of any  party  then in  breach);  provided,  however  that  the  confidentiality
provisions  contained in the first sentence of Section 15 below and Section 14.C
shall survive any such termination.

                 C.  If  Buyer  is not in  material  breach  of its  obligations
contained  herein  and if this  Agreement  is  terminated  by Buyer by reason of
Seller's breach of any  representation,  warranty or covenant  contained in this
Agreement,  or by  Seller  or  Buyer  by  reason  of  the  failure  of  the  CCC
stockholders  to adopt this Agreement or if the meeting of CCC  Stockholders  to
approve  this  Agreement  is not  held,  and  at any  time  on or  prior  to the
expiration of eighteen 18 months  following  termination  of this  Agreement,  a
definitive agreement is entered into for the acquisition of all or substantially
all of the Sellers'  equity or assets with a person other than Buyer,  or any of
its  affiliates at an aggregate  purchase  price in excess of the Purchase Price
contemplated in this Agreement,  then CCC shall pay Buyer, upon Buyer's request,
$500,000.  The Sellers  acknowledge that the agreement contained in this Section
14.C are an integral part of the transactions contemplated by this Agreement and
that,  without  these  agreements,  Buyer  would not enter into this  Agreement.
Accordingly, if CCC fails to pay any amounts pursuant to this Section 14.C, and,
in order to obtain such  payment,  legal action is commenced  which results in a
judgment  against CCC therefor,  CCC will pay the plaintiff's  reasonable  costs
(including  reasonable  attorneys' fees) in connection with such suit,  together
with interest computed on any amounts  determined  pursuant to this Section 14.C
(computed  from  the date or  dates  incurred)  at the  prime  rate of  interest
announced from time to time by Citibank, N.A. CCC's obligations pursuant to this
Section 14.C will survive any termination of this Agreement.


                  Section 15.  Confidentiality:

                  All  information  and  documents  relating  to the  Facilities
obtained  pursuant  to Buyer's due  diligence  investigation  and not  otherwise
publicly available shall at all times be



                                       23

treated as  confidential  by Buyer,  and shall not be  disclosed to or discussed
with any third party (except Buyer's  accountants,  bankers,  counsel, and other
advisors) or otherwise  utilized for any purpose  unrelated to the  transactions
contemplated  by this  Agreement.  In the event this Agreement is terminated for
any reason,  all documents  relating to the Sellers and the Business obtained by
Buyer from  Seller in Buyer's  due  diligence  investigation  shall be  promptly
returned to the Sellers.

                  Section 16.  Miscellaneous:

                  A. The  parties  agree,  after the  Closing,  to do,  execute,
acknowledge,  and deliver all such further acts, deeds, assignments,  transfers,
conveyances, powers of attorney, and assurances as may be required to consummate
the transactions contemplated hereby.

                 B. Subject to the terms and conditions  hereof,  this Agreement
shall be binding  upon and inure to the benefit of the parties  hereto and their
respective administrators, successors, and assigns.

                  C. Any notice, request,  instruction,  or other document to be
